Great for the Hearing Challenged

My Dad is hard-of-hearing with no hearing aid. He receives visitors every now and then and can’t hear the standard doorbell.We bought this product and taped a transmitter to the front door and put the receiver in his room. He never misses a visitor now! We keep the extra transmitter with us, in case the visitor is shy, and use it as needed.Not sure about the weatherproof because our door is under an awning.Very simple to install. Plug and Ring!

Pros
  • 300 M/1,000 FT ULTRA LONG WIRELESS RANGE: Will not interfere with other equipment in your home or those of your neighbors; ensures you will never miss a visitor, even if you are a few rooms away or on another floor
Cons
  • The doorbell may not have enough volume control options to suit individual preferences
